SPECIFICATION forming part of Letters Patent No. 739,840, dated September 29, 1 903. Application filed January 2, 1903. Serial No. 137,494.. (No model.)

To ctZZ whom, it may concern:

Be it known that I, NARCISSE N. S. DAUDE- LIN, a citizen of the United States, residing at Fall River, in the county of Bristol and- State of Massachusetts; have invented certain new and useful Improvements in Thread- Board Lifters, of which the following is a specification.

My invention relates to devices for the automatic elevation of thread-boards devised to prevent the ballooning of the threads at a point intermediate the thread-board and traveler of spinning or twisting frames.

Various methods have been devised for attaining this end; but simplicity and accuracy of operation are best attained by the mechanism hereinafter described, and illustrated in the accompanying drawings, wherein- Figure 1 is a front elevation of a section of a ring-spinning frame containing my new mechanism; Fig. 2, a transverse section of the same, showing my improvement in end elevation; Fig. 3, a plan view of the latter, and Fig. 4; detail views of the clamping-block for supporting the curved-lever bearing.

Like reference-figures indicate like parts I throughout the views.

Referring to the drawings, 1 represents the common form of spinning or twisting frames, whereon are vertical spindles 2, driven by bands 3 from the drum 4. The ring-rails 5 are vertically movable to feed the thread to the bobbins 6 through thetraveler 7. The thread is supplied by the rolls 8, mounted in the frame 1 above the hinged thread-board 9, and traverses the guide-eyes 10 upon the outer margin of the 'thread board. The rocker-rail 11 traverses the frame below the spindles and parallel thereto, but in a higher plane longitudinally reciprocates the usual rocking-arm rod 12, vibrated by the rocking arm or lever 13, tightly mounted on the builder rock-shaft 14. The lifting rod or poker 16 is raised by the lifting-rod lever 15,

which is also fixed to the rock-shaft 14. It is in conjunction with these familiar parts that my mechanism is utilized.

Bolted to the beam of the frame, on either side thereof,are upright vertically-adj ustable supports 18, in whose tops are mounted rollone 19, over which run chains 20 20, whose ends engage the extremities of upwardlyextending curved arms 21, which are bolted to the thread-boarded The roller-terminals of the chains 20 and 20 converge in a single elongated link 22. s'arily of greater length to traverse the frame, passes over guide-rollers 43 4-it,m0unted upon the upper portion of'the frame. The result of this arrangement of the chains is the simultaneous raising and lowering of the arms 21 and their connected thread-boards whenever the link 22 is vertically depressed and raised. The vertical reciprocation 'of this link is produced as follows:

Olamped to the rock-lever 13, near its pivoted extremity, is a rearwardly-projecting flat bar 24, whose extremity is pierced to receive the threaded rod 25, which is adjustably retained in engagement therewith by a nut 40. The opposite end of the rod 25 is pivotally joined to the lower end of a curved lever 26, which in turn is pivotally mounted near its center on a pin 27, projecting from the rear of a plate 28, which will be later referred to. From the upper end of lever 26 projects a pin 29, which traverses the link 22 and engages the latter by means of a nut 41 upon its threaded end. To the rocker-rail 11 at a point opposite the link 22 is fixed a rearwardly-projecting flat bar 30, with its end bent upward. Immediately above the bend of the rod 30 is a rearwardly-projecting pin 31, fixed thereto, which serves as a stop to the excessive travel of the lever 26. This pin is longitudinally adjustable in the slot 32 by a nut and bolt 33. Ata higher point upon the bar 30 is a block 34, one of whose faces is vertically recessed at 35 to receive said bar,

the opposite face being provided with a transverse channel 36 to accommodate the plate 28, which is adjustable by means of a bolt 37, which traverses a hole 38 in the block 34 and an oblong slot 39 in the plate.

The operation of my novel mechanism is as follows: As the r0ck-lever13 moves toward the right as viewed in Fig. 1 the rod 25, acting upon the curved lever 26, causes the latter to pull the link 22 downwardly. When the lever 13 oscillates to the left, the tension on thelink 22 is relieved and the latter moves upwardly under the influence of the Weight of the curved arms 21. During the travel of the rock-lever 13 to the rightthe ring-rails 5 The latter chain, neces- ICO - gradually rise in response to the lifting-rods inanelevated position.

16 and levers 15. It will thus be seen the upward and downward travel of the ringrails 5 are contemporaneous with the rise and fall of the thread-boards 9, whereby the desired end is attained.

It is obvious that the arc of travel of the thread-board can be raised or lowered by allowing the bar 25 to project a greater or less distance through the fiat bar 2t.

In doffing the entire mechanism must be stopped and the arms 21 be temporarily held This end is attained by drawing downwardly the long link 22, so as to bring the lever-pin 29 to a position near the top of the link, where by means of the nut 41 the pin and link are engaged until necessary to lower the arms 21 and operate the frame.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a spinning-frame, the combination with the builder rock-1e ver of a bar fixed thereto, a pivoted lever connected at one extremity to the bar, a hinged thread-board, an arm fixed to the thread-board, and connecting means intermediate said arm and the other extremity of the pivoted lever as and for the purpose set forth.

. 2. In a spinning-frame, the combination with the rock-lever of a bar fixed thereto, a

pivoted lever connected at one extremity to the bar, means upon the pivoted lever for adjustably engaging a chain, a hinged threadboard, an arm fixed to the thread-board,and a chain connecting said arm with the other extremity of the pivoted lever, as and for the purposeset forth.

3. In a spinning-frame, the combination with the rock-lever of a bar fixed thereto, of a pivoted lever connected at one extremity to the bar, ahinged thread-board, an outwardlycurved arm fixed to the thread-board, an upright arm projecting from the upper part of the frame, a roller mounted in the upright arm, and a chain traveling upon said roller, attached to the free extremity of the curved arm and to the pivoted lever, as and for the purpose set forth.

4. In a spinning-frame, the combination with the builder rock-lever ofa bar fixed thereto, a pivoted lever connected at one extremity to the bar, hinged thread-boards, arms fixed to the thread-boards, and connecting means intermediate said arms and the other extremity of the pivoted lever as and for the purpose set forth.

5. In a spinning-frame, the combination with the rock-lever of a bar projecting therefrom, andprovided with a transverse passage, a threaded bar traversing said passage, means upon the threaded bar for adjusting the latter longitudinally,ra pivoted lever connected at one extremity to the bar, a hinged thread-board, an arm fixed to the threadboard, and connecting means intermediate said arm and the other extremity of the pivoted lever as and for the purpose set forth.

6. In a spinning-frame, the combination with a hinged thread-board of, an arm fixed thereto, a chain fixed to the free end of the arm, an oblong link on the opposite end of the chain, a pivotedlever mounted adjacent the link, clamping means upon the extremity of the pivoted lever for'adjustably engaging the oblong link, and means for actuating the pivoted lever, as-and for the purpose set forth. I

In testimony whereof I have affixed my signature in presence of two witnesses.
